There is an excellent booklet called "Understanding Reptile Parasites" by Roger J. Klingenberg. The book was printed by the AFH (American Federation of Herptoculterists). At one time I routinely wormed in the fall with Panacur paste. It is primarily for nematodes, but can also have some effect on tape worms(cestodes). The common dosage of Panacur's active ingredient Fenbendazole was 25mg/kg of reptile. It is easily fed in a hollowed out fig to cyclura. I have never had problems using it, and it is considered a drug of choice for nematodes. Others have observed temporary weight loss in their cyclura after using it. Good luck.
